The short week of preparations also played a role in the decision, as Rapoport noted Trubisky could probably play if this were a Sunday game.

The Bears conducted a walkthrough practice Wednesday and officially listed Trubisky, who was estimated as not practicing, as doubtful to play.

Daniel has started just two games in his nine-year career, but hasn't attempted a regular-season pass since the 2016 season while with the Philadelphia Eagles. He has appeared in 60 career games and completed 51 of 78 passes for 480 yards and a touchdown with an interception and is 1-1 as a starter.

What will help Daniel's transition from backup to starter against the Lions, however, is his familiarity with head coach Matt Nagy's offensive scheme. The two were together with the Kansas City Chiefs from 2013 to 2015 before reuniting in Chicago during the offseason after Nagy became the head coach.

With Trubisky not expected to play, the Bears signed quarterback Tyler Bray to the active roster from the practice squad. Bray also comes with knowledge of the scheme, having spent the past five seasons with Nagy in Kansas City.
